DESCRIPTION
The TDA7335 is a monolithic BICmos IC de-
signed for use in stereo cassette player systems.
The device includes two separate audio channels
composed by low noise preamplifier, Dolby B
noise reduction system and Audio Music Sensor.
The dual preamplifier contains mute, autoreverse,
metal/normal facilities for amplification of low level
signal in applications requiring very low noise per-
formances.
Each channel consists of two cascaded opera-
tional amplifiers.
The first one, AMP1, has a fixed gain of 36dB,
low noise forward/reverse switchable input, and
allows magnetic heads connection directly to
ground. The second one, AMP2, is a standard op-
erational amplifier whose equalizing external
components fix the frequency response.
The Audio Music Sensor circuit detects the inter-
program space and then the starting point of mu-
sical programs (the interprogram time and pro-
gram detection time are externally selectable).
The device contains Dolby B decoder NR chains
requiring very few external components and do
not require coils.
